Male Hormones

The male hormones of interest, are the ones responsible for controlling the production of testosterone and sperm in the testes. Luteinising Hormone (LH) causes the testicles to produce testosterone. Follicle Stimulating Hormone (FSH) helps control the production of sperm. Measuring the levels of LH, FSH and Testosterone is rarely required.

The only reason to explore whether a man’s male sex hormones are functioning properly is if the semen analysis test shows a very low sperm count. A fertility doctor would always examine the testicles first but an abnormal semen analysis report may trigger hormone testing. It is only usually required if there are no sperm (azoospermia) in the ejaculate or if the semen analysis is very poor and the testicles feel atrophied and small.
